-------------------------------------------
Hi Eli,
Thanks a lot for the documenting all the configurations.
Here are the list of HA related configurations i came across.
{code}
public static final String DFS_CLIENT_FAILOVER_PROXY_PROVIDER_KEY_PREFIX =
"dfs.client.failover.proxy.provider";
public static final String DFS_CLIENT_FAILOVER_MAX_ATTEMPTS_KEY =
"dfs.client.failover.max.attempts";
public static final int DFS_CLIENT_FAILOVER_MAX_ATTEMPTS_DEFAULT = 15;
public static final String DFS_CLIENT_FAILOVER_SLEEPTIME_BASE_KEY =
"dfs.client.failover.sleep.base.millis";
public static final int DFS_CLIENT_FAILOVER_SLEEPTIME_BASE_DEFAULT = 500;
public static final String DFS_CLIENT_FAILOVER_SLEEPTIME_MAX_KEY =
"dfs.client.failover.sleep.max.millis";
public static final int DFS_CLIENT_FAILOVER_SLEEPTIME_MAX_DEFAULT = 15000;
public static final String DFS_CLIENT_FAILOVER_CONNECTION_RETRIES_KEY =
"dfs.client.failover.connection.retries";
public static final int DFS_CLIENT_FAILOVER_CONNECTION_RETRIES_DEFAULT =
0;
public static final String
DFS_CLIENT_FAILOVER_CONNECTION_RETRIES_ON_SOCKET_TIMEOUTS_KEY =
"dfs.client.failover.connection.retries.on.timeouts";
public static final int
DFS_CLIENT_FAILOVER_CONNECTION_RETRIES_ON_SOCKET_TIMEOUTS_DEFAULT = 0;
{code}
BTW, can we move above configuration keys to under the comment '// HA related
configuration' in DFSConfigKeys class?.
